There are two versions of the converter box. The RC-DT09 which does not have the analog pass through and The RCDT09A which does have the analog pass through Otherwise the units are the same. The Sensar or Batwing antenna should be fine for most stations. Some channels will move when the transition happens and depending on where you are your signal may improve or get worse based on what the broadcaster does. For the most part, if you are happy with the Sensar for analog, you will be happy with it for digital. Many of the local stations are not broadcasting digital yet.
